USB-C and USB-A card reader for SD and microSD

This external reader connects to USB-C or USB-A ports on laptops, tablets, smartphones and desktops. It accepts full-size SD and microSD cards including SDHC, SDXC and MMC formats. The compact black housing measures .40" x .80" x 3.10" and requires no driver installation.

Dual USB 3.0 interface at 5 Gbps

The device provides one USB Type-C connector with 24 pins and one USB 3.1 Type-A connector operating at Gen 1 speed. Both interfaces support data transfer rates up to 5 Gbps and are backward compatible with USB 2.0 hosts. Thunderbolt 3 ports also accept the USB-C plug.

Sustained transfers limited by card speed

Under continuous load the reader delivers whatever throughput the inserted SD or microSD card can sustain. The USB 3.0 link does not bottleneck typical UHS-I media, but UHS-II or faster cards will not reach their peak rates through this 5 Gbps interface. Heat buildup is negligible in the small enclosure.

Perguntas sobre este artigo

What does the 5 Gbps figure mean when I am copying files from an SD card?

It is the USB 3.1 Gen 1 interface ceiling; real-world throughput will be lower and depends on the card's own read speed.

Which USB standard does the Type-C port use and what does that limit?

The Type-C port runs USB 3.0, so the 5 Gbps link caps total bandwidth for both slots combined.

How much space does the reader need to sit beside a laptop port?

The body measures 0.40" x 0.80" x 3.10", so it fits alongside most adjacent ports without blocking them.
